Larvik – stone with distinctive iridescent effect
The Larvik quarry on the south coast of Norway was opened specifically for rock armour (EN13383) production, and it’s the only dedicated rock armour quarry in Europe. The materials used by Norsk Stein is a by-product from the dimension stone industry, where only around ten percent of quarried rocks is deemed usable. The dimension stone trade under names such as Larvikite and Blue Pearl and are used in facades, gravestones or other form of decorative stone; the stone is known for its distinctively spectacular iridescent effect.
Norsk Stein use the by-product of this granite known for its unique hardness as rock armour, mainly used in coastal and river protection works.
